Merge.dev

Built for software developers, B2B SaaS product teams, and enterprise technology companies of all sizes; it is a developer platform rather than a direct end-user tool for residential or commercial trade contractors.

REST API

API access requires authentication via Bearer API keys and account tokens. Merge offers a freemium Launch tier where the first 3 production linked accounts are free ($650/month base up to 10 accounts, plus $65/month per additional account). Advanced features including custom field mapping, field-level scopes, and custom sync frequencies are gated behind paid Professional and Enterprise custom contracts.

Rate limits are enforced per Linked Account based on tier: Launch (100 requests/min), Professional (400 requests/min), and Enterprise (600 requests/min). Write operations have narrower coverage than reads across integrations. Access to custom fields and configurable sync schedules requires Professional or Enterprise plans, and sync resyncs are limited by allocated sync credits.

Merge.dev (Merge Unified API) is a developer integration platform for B2B SaaS rather than trade/construction field management software. Its native AI capabilities center on AI agent infrastructure, specifically Merge Agent Handler (launched GA October 2, 2025) and the Merge MCP Server (GA released April 2025), which allow third-party AI agents and LLMs to authenticate, query, and execute actions across 220+ SaaS integrations via the Model Context Protocol (MCP). It does not contain native field service automation tools such as estimating or CSR.

None. Merge.dev does not offer native AI-powered dispatching or scheduling software for field operations. In Merge's technical documentation, 'dispatch' refers strictly to API request routing within its Agent Handler gateway.

None. Merge.dev does not provide native AI invoicing or AP/AR automation tools. It offers an Accounting Unified API and corresponding MCP tool endpoints, which allow external AI agents to read/write data in third-party accounting platforms (e.g., QuickBooks, NetSuite), but it does not ship built-in financial AI features.

Yes (Shipped/GA). Merge.dev offers the Merge MCP Server (released April 2025) and Merge Agent Handler (launched October 2, 2025). This infrastructure exposes Merge's unified API connectors as Model Context Protocol (MCP) tools for LLMs (such as Claude Desktop, Cursor, and custom AI agents), enabling natural language queries, entity creation, and updates across connected SaaS systems, enforced by enterprise security rules, DLP, and logging.

Merge.dev connects to general cloud and enterprise accounting systems including QuickBooks Online, Sage Intacct, Sage Business Cloud, NetSuite, Xero, FreshBooks, Zoho Books, Wave Financial, Clear Books, FreeAgent, Microsoft Dynamics 365 Business Central, Moneybird, Oracle Fusion Cloud ERP, and Workday. It does not natively support specialized construction accounting systems such as Foundation Software. For general project and workflow management, Merge connects to tools under its Ticketing Unified API (e.g., Asana, ClickUp, Jira, Basecamp, Azure DevOps), but does not maintain native connectors for trade/construction-specific field platforms like Procore or ServiceTitan.

Merge.dev features a public Integrations Directory listing over 240 supported applications across categories such as Accounting, HRIS, ATS, CRM, Ticketing, File Storage, Chat, and Knowledge Base. It also maintains a dedicated Partner Network directory and provides an Integration Metadata API (`/api/integrations`) allowing B2B software vendors to programmatically power in-app integration marketplaces.

Typically days to a few weeks for software developers to build integrations, with end-user account linking taking minutes via Merge Link.

No paid implementer or VAR required; Merge.dev is a developer-first API middleware platform designed for direct integration by software engineering teams.

Merge.dev is a modern B2B integration infrastructure platform that provides unified APIs across HRIS, ATS, payroll, CRM, accounting, ticketing, and file storage categories, as well as AI agent governance tools (Merge Agent Handler). It is not a field-level software product built directly for U.S. trade or construction contractors; rather, it is a developer platform used by software vendors (including construction-tech SaaS providers) and enterprise IT teams to build and maintain third-party software integrations.

Merge demonstrates strong growth momentum as a modern, category-leading platform. Named a sole Category Leader by G2 and included on the Forbes Fintech 50 and Forbes Next Billion-Dollar Startups lists, Merge has raised $75 million in total capital, most recently a $55 million Series B led by Accel in October 2022 at a $325 million valuation. Company financials reflect revenue expansion from $8 million in 2022 to $14 million in 2023 and an estimated $20.8 million in 2024.
